Pasta with Leek, Pepper, and Chive Sauce

(The leeks contribute to make a fine pasta sauce because they cook quickly to a buttery sweetness. Peel the bell peppers with a vegetable peeler; the pepper strips will become softer and adhere to the pasta better without the peel. The recipe suggests that you use ear-shaped orecchiette, but any small pasta will work in this recipe. Try using whole wheat orzo.)
